Modbus MCP Server

Example Use Cases

• 1

  Read and write Modbus TCP device registers using human-readable names instead of raw addresses.

• 2

  Simulate Modbus devices for testing without physical hardware.

• 3

  Seamless integration with local LLMs via OpenClaw for natural language control of industrial devices.

Description

This MCP server simplifies interaction with Modbus TCP devices by allowing natural language control and semantic register mapping through YAML device profiles. It supports automatic data type conversion, includes a built-in Modbus TCP simulator for testing without hardware, and offers multiple MCP tools for both profile-based and raw register access. The server is Docker-ready and integrates with local LLM agents via an OpenClaw skill wrapper, enhancing usability and automation.
